I'm surprised this wasn't announced on Monday after Disney's movie makes over $200 million dollars but Disney CEO Bob Iger announced that the company is developing a sequel. The film’s success "is a great illustration of why we like Marvel so much." Demand for Avengers merchandise has been strong, he added.

Happy to see this Will be interesting to see which direction they take with it

Whedon originally indicated that he favoured a smaller and more "personal" sequel.

But with the Infinity Gauntlet being glimpsed in Thor, Loki possibly (?) using the "Mind Gem" in The Avengers and the tease of Thanos at the end of The Avengers, it seems pretty likely that they'll be going with another substantial threat.

I hope they go with some mortal foes like Zemo and the Masters of Evil, or introduce Hank Pym, Janet Van Dyne, Ultron and The Vision. Leave the space stuff to Thor or the rumoured Guardians of the Galaxy flick.

Even though the last announcement was publicly confirmed, it still seems like a big spoiler to me, so I hid it just in case anyone doesn't want to know that one.

And while Scarlett, Mark, Jeremy, and the two Chris's are all expected to return as Black Widow, Bruce Banner, Hawkeye, Thor, and Captain America respectively, their casting has not yet been publicly confirmed, even though filming is expected in mere weeks.

- I love Wanda's appearance. It's pretty much exactly how I hoped they'd do her. Kind of bohemian/gypsy style.- I'm glad that they have Pietro in blue, but (from this pic) his outfit looks awfully generic. I'm not worried though, as we'll see what we end up with in the finished film. Also, I'm totally ok with them having him with similar coloured hair to his sister instead of white. It makes sense.- Looks like the destruction with be upped in a big way, judging by the shot with Hulk & Natasha.- HULKBUSTER IRON MAN vs HULK!!! - ...and Tony in a tech lab. Not much to say about that.
